The Quantum Surge: A Glimpse into the Future of Cryptography

Blog Post

In the fast-evolving field of quantum computing, the pace of innovation is nothing short of breathtaking. The cyber defenses we’ve built on encryption face their most formidable challenge yet. A few recent developments demonstrate the exciting progress and the urgency of this quantum race.


China’s Quantum Leap with Jiuzhang 3.0

China’s unveiling of the “Jiuzhang 3.0” quantum computer prototype is an example of the rapid strides in quantum research. This photon-based quantum computer has set new records, emphasizing its ultra-fast parallel computing capabilities. These advancements demonstrate progress in speeding up quantum applications, useful for big data optimization to drug analysis. The Jiuzhang is designed for Gaussian boson sampling. While this type of quantum computer is useful for specialized tasks, this isn’t a general quantum computer that will run Shor’s algorithm. That said, its existence and fast progress demonstrate that the quantum age is not coming; it’s here.


A Quantum Twist to Internet Encryption

A recent paper by Oded Regev of New York University became a topic across the security community. Regev introduced a novel quantum algorithm that presents a different approach to factoring large numbers, the cornerstone of internet encryption. This algorithm can reduce the logical steps required for factoring and, therefore, decryption. The algorithm is still in the early stages of development, and it remains to be seen whether it will be more efficient than Shor’s algorithm or if it can be practically implemented. However, introducing such a concept shows a vibrant avenue of research, increasing efficiency and discovering new ways to solve the factoring problem. As our CTO Denis Mandich has said, this is one area “…where the first to market wins everything.”


Illuminating Quantum Errors: A New Paradigm

Researchers at Princeton University, led by Jeff Thompson, unveiled a technique that makes it ten times easier to correct errors in quantum computers. Their approach identifies errors as they occur in real time, measuring subtle manipulations of atomic energy levels. As error correction improves, so does the feasibility of larger quantum computers with far more qubits available for computation. This brings the timeline for solving significant problems or breaking encryption even closer.


The Silent Threat: Hidden in Router Firmware

A recent alert issued by cybersecurity officials, including the United States Cybersecurity and Infrastructure Security Agency (CISA), revealed that a China-linked hacking group, dubbed BlackTech, has been compromising routers in the US and Japan. By secretly modifying their firmware, this group has been moving stealthily around company networks. Such covert operations highlight the “Harvest Now, Decrypt Later” strategy in action, where encrypted data is accumulated today, with the anticipation of quantum capabilities to decipher it in the future. This incident is one of many we frequently hear about concerning data capture. Time and again, encrypted data proves to have immense value for adversaries.


Rethinking Our Quantum Timelines

These developments, along with other recent breakthroughs in qubit counts, noise reduction, and qubit stability, are clear indicators of the breadth and speed of the quantum research landscape on all the key technological barriers. They signal the timeline for a cryptographically relevant quantum computer might be shorter than previously anticipated. Nation-states and malicious actors will silently advance their quantum capabilities, ready to exploit them. This stealthy progress threatens wealth, privacy, and secure data transfer on a global scale. Given the prolonged transition to new cryptographic standards and the implications of data retention policies, the time to act is now.
